Paul H. Steen
Dr. Paul H. Steen is a Professor in the School of Chemical and Biomolecular Engineering, with field affiliations in Applied Mathematics, Theoretical and Applied Mechanics and Mechanical and Aerospace Engineering. He holds the Maxwell M. Upson Chair in Engineering.
His expertise is in the stability of systems of liquids and gases and stability of dynamical systems, more broadly. A current focus is on deformable liquid/gas interfaces, including the shape-change of constrained drops, bridges, beads and rivulets. Steen co-invented a switchable adhesion device wherein interfaces are purposely reconfigured via electro-osmotic pumping. He is also an expert in planar-flow spin casting, a very different application in which molten metals are rapidly solidified into thin sheets, and wherein instability of the molten/gas interface can lead to undesirable reconfigurations that get frozen in the product. He is a fellow of the American Physical Society (1996). He served as an Associate Editor of the Journal of Fluid Mechanics from 2000-2011. He has been active in governance of the American Physical Society (APS), Division of Fluid Dynamics (DFD) as chair of the Fluid Dynamics Prize Selection Committee, chair of the Acrivos Dissertation Award Committee, member of the Nominations, Executive, Program, Publications and Frenkiel Award Committees. He has co-edited "A Gallery of Fluid Motion," a DFD project published by Cambridge University Press. He has delivered keynote talks at Gordon Conferences, APS, APS/DfD, AICHE and ACS meetings. He has coauthored more than 70 papers, has edited books and holds a number of patents and referees regularly for JFM, Science, Nature and PNAS, among others.
Prior to coming to Cornell, Steen received his PhD from The Johns Hopkins University in 1981 and held a post- doctoral position in Chemical Engineering at Stanford University, after having completed undergraduate degrees in Engineering and English Literature at Brown University. At Cornell, he has served as Director of Graduate Studies for Chemical Engineering. He was awarded the Alexander von Humboldt Fellowship, enabling visits to Karlsruhe and the Max Planck Institute in Goettingen, Germany. He has been a Senior Guest Scientist at the Forschungszentrum Karlsruhe and a Visiting Scientist with the Physics of Fluids group at the University of Twente, The Netherlands.
